This would be great, but...
I must be missing something; running 2.8.10 on fbsd.
When I click on the alignment buttons, nothing happens, and they don't change 
appearance on mouse-down or mouse-up.
I can't quite tell from the glyphs, but they look like they may be greyed out; 
at
least they are overall a lot lighter than most of the toolbox glyphs; they look 
about
like the bucket-fill tool.  The "Offset" text box is active and allows changes,
and the reset options does its thing.
No error messages that I can see.

Any ideas what would cause them to be inactive?
All other tools seem to work.
